It is narrated from Sayyiduna Fadl bin Abbas (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) seated him behind him (on his mount) on the morning of Muzdalifah, and he (peace and blessings be upon him) continued reciting the Talbiyah until he stoned Jamrat al-Aqabah. He said: He (peace and blessings be upon him) threw seven pebbles at it from below, saying one Takbir with each pebble. Then the Messenger of Allah (peace and blessings be upon him) offered his sacrifice and said: "I have sacrificed here, and the whole of Mina is a place of sacrifice, so sacrifice in your own places."
